Loetz Candia Papillon Art Nouveau glass vase, Bohemia, circa 1899/1900, the vase with a flared neck and three dimples to the body, the clear glass with splashes of iridescence.
The closest paper pattern I can find from the book Lótz - Bóhmisches Glas 1880 bis 1940 is in photo 7. More Candia Papillon examples can be seen at loetz.com
